Forget that first ex-boyfriend — Kate Walsh is on to bigger and better guys. The Private Practice star is trading up with her new fragrance, Billionaire Boyfriend, the second in her “Boyfriend” series of scents.

“The idea was always luxe,” Walsh tells PEOPLE. “It’s kind of a throwback to times when things were just sexy and romantic, and that fantasy of James Bond movies, Monte Carlo, driving down the coast in a sports car … la dolce vita.”

The fragrance mixes feminine and masculine notes of black jasmine amber, fruits of bergamot, tangerine, orchid, gardenia and sandalwood to create a super-rich scent. “It’s yummy,” Walsh says. “For people familiar with the original Boyfriend, they’ll recognize it in the bottom notes, but with the additions of a big, bad floral.”

Billionare Boyfriend comes with a fancy bottle, too, inspired by “a big magnum of Dom [Perignon],” Walsh says. “I wanted to have this bottle feel very old school, a nod to old-world Europe.”

The “webemercials” for the scent were just as cool to create: Walsh and her team filmed them over a long weekend at the Atlantis resort in the Bahamas.
